Battles of Ideas Between the Legal and the Legitimate
This chapter discusses how social psychology can offer theoretical contributions for a better understanding of the relations between the institutional and public spheres and how this may impact change in ecological matters. First, it introduces the difference between natural and agreed—or chosen—limits to human action and draws on Sophocles’s Antigone to illustrate this and discuss how legitimacy has roots in the many heterogeneous values of the public sphere/consensual universe, while legality arises from the institutional/reified sphere. Recalling some empirical research in the area of social studies of sustainability, it then shows how a social representations perspective can help us understand the dynamic and interdependent relations between the institutional or reified sphere and the consensual or common sense universe—and their implications for social change and continuity.
